Title: Storage facility for fresh food
Inventor: TAKEDA JUN
IPC: A01F25/00
Filed: 1989-03-23
Abstract: PURPOSE:To prevent excess usage of a heating unit for removal of ethylene and save electric power by accommodating an adsorbent capable of adsorption of carbon dioxide and another adsorbent capable of adsorption of ethylene in an adsorber through which the gas in a storage house is circulated. CONSTITUTION:The gas in a storage house 1 is circulated through an absorber 24 or 25 using a blower 28 so that ethylene and carbon dioxide may be adsorbed respectively by adsorbents 38 and 37 and the treated gas is returned to the storage house 1. The outside air heated by a heater 40 is passed through the adsorber 25 or 24 using another blower 39 so that carbon dioxide or ethylene may be desorbed from the adsorbent 37 or 38. The adsorbers 24 and 25 are repeatedly subjected to alternative adsorption and desorption.

Title: Beverage feeder
Inventor: UZAWA TAKASHI
IPC: F25D11/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a beverage feeder which is excellent in heat exchangeability of cooling water in a condition of an incessant vendition of beverages. SOLUTION: A quadrangular-pyramid-shaped protrusion 8 is provided on a bottom portion of a cooling water tank 1. A water flow is generated in the direction shown by the arrows in cooling water W filled in the cooling water tank 1 with the rotation of a propeller 4B in a given direction, which is fixed to a rotary shaft 4A of an agitator motor 4. By allowing the water flow to move along the inclined surface of the quadrangular-pyramid-shaped protrusion 8 to the direction of the inner wall of the cooling water tank 1, circulation of the cooling water W from the vicinity of the water surface to the bottom portion of the cooling water tank is improved, thus preventing lowering of heat exchangeability.

Title: Audio response unit
Inventor: OZAWA YUKIO
IPC: G10L13/06
Filed: 1978-06-14
Abstract: PURPOSE: To shorten the access time to an audio memory unit and simultaneously increase the number of output lines by dividing sound information into plural information groups and writing them into a line buffer which is provided correspondingly to each line and stores information temporarily.  
     CONSTITUTION: Sound information of unit length is divided into plural information groups, and block numbers are added to them. Then, they are stored previously in circulating audio memory unit 2, and sound information of unit length designated by sound read control unit 3 is read out from the start of an arbitrarily circulated information group in order by unit length and is converted to 8-bit parallel data by series-parallel converter 5 and is given to distributor 6. Distributor 6 writes the block number as an address into line buffer 7 which is assigned by talkie compilation control unit 1. PCM digital sound information transmitted from line buffer 7 is converted to an analogue code by MODEM 8 and is demodulated to sound and is outputted. Thus, the number of output lines can be increased simultaneously with shortening the access time to the audio memory unit.

Title: Reversible thermal recording medium for laser recording
Inventor: HIRAYAMA SHIGERU
IPC: B41M5/36
Filed: 1995-03-29
Abstract: PURPOSE: To obtain a reversible thermal recording medium capable of enhancing contrast and enabling recording/erasure in a noncontact state by forming an air layer between either one of a thermal recording layer and a photothermal conversion layer and a base material positioned on the side of either one of those layers. CONSTITUTION: A reversible thermal recording medium 1 for laser recording is obtained by successively laminating an air layer 52, a support part 53, a thermal recording layer 54, a light absorbing heat conversion layer 55 and a transparent protective layer 56 on a base material 51. The thermal recording layer 54 consists of a turbid part recorded by the exposure of laser beam and an unrecorded or erased transparent part and, even when resins near in refractive index each other are used in respective members, the refractive index difference at the interfaces thereof becomes large by the air layer as compared with a closely bonded case, the contrast of the turbid part is enhanced.  Since the air layer 52 acts as a heat insulating layer, recording/erasure by a contact system such as a thermal head can be made difficult and, since the air layer 52 has heat insulating effect, the utilization efficiency of laser beam at a time of exposure is enhanced.

Title: Collimation type and laser type automatic leveling instrument
Inventor: IIZUKA TADASHI
IPC: G01C15/00
Filed: 1987-03-27
Abstract: PURPOSE:To obtain an automatic leveling instrument used in the leveling in a narrow range of a civil engineering field,by making the length of the suspension line of a rectangular prism for compensation half the length calculated by adding the length from a reflecting point to a pendulumn support point to the focal distance of an objective lens. CONSTITUTION:A rectangular prism 2 for compensation is provided to the image space of an objective prism 1 whose optical axis H1 is made horizontal and the optical axis H1 is vertically bent upwardly to place a cross line R1 at the focal position thereof and said cross line R1 is magnified and collimated by an eyepiece. The prism 2 is constituted so as to be suspended by a suspension line so that the distance from the cross line R1 to a pendulum support point B becomes 1/2 the length calculated by adding the length A1B from the reflecting point A1 of the prism 2 to the support point B to the focal distance (f) of the lens 1. Automatic leveling is formed when the center of rotation of a pendulum is positioned at the distance f/2 from the cross line but, in this case, since the support point B of the pendulum is positioned at an upper part, the prism 2 moves to a prism 2' when a main body is inclined by an angle theta. Since the moving quantity of the prism 2 is a length (A1BXtheta), said quantity S is corrected by making a length A1R1 half a length (f+A1B). Therefore, the pendulum is held horizontally with good accuracy.
